Migration from GFE_BUG_V2 (and friends) to GFE_BUG
Migration from GFE_BUG_V2 (and friends) to GFE_BUG

Per go/gfe-bug-improvements GFE_BUGs are getting stable IDs to allow for monitoring and alerting. To achieve that, a temporary set of V2 macros was added and the codebase was migrated to using the V2 macros. Now that migration is complete, the old-style (sans _V2) macros were changed to also take bug_id parameter, which makes the V2 set obsolete. To complete the transition, the codebase is being migrated back to GFE_BUG macros. Once done, V2 macros will be removed.
